Abstract
The diagnostic and treatment landscapes of prostate cancer are rapidly evolving. This has led to several challenges and controversies regarding optimal management of the disease that outpace guidelines and clinical data. Multidisciplinary teams (MDTs) can be used to engage the array of specialists that collaborate to treat complex malignancies such as prostate cancer. While the rationale for the use of MDTs in prostate cancer is well known, ways to optimally use MDTs to address the challenges and controversies associated with prostate cancer management are less well understood. One area of MDT care that remains undefined is how MDTs can most effectively provide guidance on clinical decision-making in situations in which information from novel diagnostic testing (genetic testing, molecular imaging) is substantially different from the established clinical risk factors. In this review, we provide a clinical perspective on ways that MDTs can be used to address this and other challenges and controversies across the prostate cancer disease continuum, from diagnosis to end-of-life considerations. Beyond clinical scenarios, we also review ways in which MDTs can mitigate disparities of care in prostate cancer. Overall, MDTs play a central role in helping to address the daily vexing issues faced by clinicians related to diagnosis, risk stratification, and treatment. Given the accelerating advances in precision medicine and targeted therapy, and the new questions and controversies these will bring, the value of MDTs for prostate cancer management will only increase in the future.

Life after Cell Death-Survival and Survivorship Following Chemotherapy. Cancers (Basel) 2021; 13:cancers13122942. [PMID: 34208331 PMCID: PMC8231100 DOI: 10.3390/cancers13122942] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Revised: 06/06/2021] [Accepted: 06/09/2021] [Indexed: 12/21/2022] Open
Abstract
Simple Summary Treatment of aggressive cancers often relies on chemotherapy. This treatment has improved survival rates, but while effective at killing cancer cells, inevitably it also kills or alters the function of others. While many of the known effects are transient and resolve after treatment, as survival rates increase, so does our understanding of the long-term health costs that accompany cancer survivors. Here we provide an overview of common long-term morbidities known to be caused by conventional chemotherapy, including the risk of relapse, but more importantly, the cost of quality of life experienced, especially by those who have cancer in early life. We aim to highlight the importance of the development of targeted therapies to replace the use of conventional chemotherapy, but also that of treating the patients along with the disease to enable not only longer but also healthier life after cancer. Abstract To prevent cancer cells replacing and outnumbering their functional somatic counterparts, the most effective solution is their removal. Classical treatments rely on surgical excision, chemical or physical damage to the cancer cells by conventional interventions such as chemo- and radiotherapy, to eliminate or reduce tumour burden. Cancer treatment has in the last two decades seen the advent of increasingly sophisticated therapeutic regimens aimed at selectively targeting cancer cells whilst sparing the remaining cells from severe loss of viability or function. These include small molecule inhibitors, monoclonal antibodies and a myriad of compounds that affect metabolism, angiogenesis or immunotherapy. Our increased knowledge of specific cancer types, stratified diagnoses, genetic and molecular profiling, and more refined treatment practices have improved overall survival in a significant number of patients. Increased survival, however, has also increased the incidence of associated challenges of chemotherapy-induced morbidity, with some pathologies developing several years after termination of treatment. Long-term care of cancer survivors must therefore become a focus in itself, such that along with prolonging life expectancy, treatments allow for improved quality of life.

The Quandary of DNA-Based Treatment Assessment in De Novo Metastatic Prostate Cancer in the Era of Precision Oncology. J Pers Med 2021; 11:330. [PMID: 33922147 PMCID: PMC8143497 DOI: 10.3390/jpm11050330] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Revised: 04/08/2021] [Accepted: 04/20/2021] [Indexed: 12/19/2022] Open
Abstract
Guidelines for genetic testing have been established for multiple tumor types, frequently indicating the most confident molecularly targeted treatment options. However, considering the often-complex presentation of individual cancer patients, in addition to the combinatorial complexity and inherent uncertainties of molecular findings, deriving optimal treatment strategies frequently becomes very challenging. Here, we report a comprehensive analysis of a 68-year-old male with metastatic prostate cancer, encompassing pathology and MRI findings, transcriptomic results, and key genomics findings from whole-exome sequencing, both somatic aberrations and germline variants. We identify multiple somatic aberrations that are known to be enriched in prostate cancer, including a deletion of PTEN and a fusion transcript involving BRCA2. The gene expression patterns in the tumor biopsy were also strikingly similar to prostate tumor samples from TCGA. Furthermore, we detected multiple lines of evidence for homologous recombination repair deficiency (HRD), including a dominant contribution by mutational signature SBS3, which is specifically attributed to HRD. On the basis of the genomic and transcriptomic findings, and in light of the clinical case presentation, we discussed the personalized treatment options that exist for this patient and the various challenges that one faces in the process of translating high-throughput sequencing data towards treatment regimens.
